WINDOW_LOCK

What it is

Window Child Lock

True indicates the window is child-locked.

This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x13200bc4 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x03000000	WINDOW
Type	0x00ff0000	0x00200000	BOOLEAN
Ordinal	0x0000ffff	0x00000bc4	0xbc4

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

boolean value =
        mgr.getBooleanProperty(VehiclePropertyIds.WINDOW_LOCK, areaId);

This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
